piKeyPass was designed to provide the functionality of providing a unique password based on a date. One use for this is if you maintain a support contract for your systems, you can put piKeyPass in your system and when the contract expires, you can have your system refuse login. If you then want to give your clients restricted access they can phone you up and request a password and you can provide this. Password will change every day and will not follow a recognisable pattern so your clients will not be able to guess the password for the next day.
There is no need to worry about other piKeyPass users being able to crack your passwords as you provide a unique key with which the passwords are generated, so you will be the only person able to provide the codes that will work.
